Penggunaan panel surya banyak dimanfaatkan masyarakat karena mampu bekerja menyerap energi matahari untuk menghasilkan sumber energi listrik, akan tetapi pergerakan panel surya kearah cahaya matahari masih bersifat manual (dibantu dengan manusia). Sistem terintegrasi Internet of Things bertujuan untuk memantau kerja dari panel surya dengan cara memperlihatkan sistem monitoring jarak jauh yang memanfaatkan jaringan internet. Variabel yang dimonitoring yaitu varibel pergerakan panel surya yang terdiri dari nilai tegangan analog, intensitas cahaya matahari, nilai kemiringan, posisi dan kondisi cuaca panel surya. Pada pengujian sudut pergerakan motor pengaturan derajat kemiringan dapat diatur pada posisi maksimal cahaya matahari. Posisi maksimal didapat sebesar 125o sejalan dengan intensitas cahaya yang didapat sebesar 1680 Lux, menghasilkan tegangan rata-rata sebesar 20,22 V, arus sebesar 2,10 A dan daya sebesar 43,07 W.

Efarina Etaham Hospital provides Covid-19 vaccination services for the community. One of the factors that influence people not to vaccinate is the lack of knowledge or education about the vaccination process. This is proven by the fact that there are still many people in the Efarina Etaham Hospital environment who have not carried out vaccinations. For this reason, this research will provide solutions to solve these problems by utilizing technology. The need for education regarding the importance of vaccination will be poured into applications based on augmented reality. This application will display vaccine introduction, information on the Covid-19 vaccine, and how the vaccine works in the human body.

Community organization is a group formed by the community voluntarily based on the common aspirations, needs, and goals to be achieved. This community organization is not just built, but must have a clear permit. Many community organizations are formed in every region, not least in the province of North Sumatra. The agency that oversees all these organizations is the National and Political Unity Agency (BKBP) of North Sumatra Province. However, there is a current problem that is experienced, namely the absence of a forum that directly connects BKBP with existing community organizations, making it difficult for BKBP to monitor, know the location of the organization, and also make it difficult for the organization in terms of registering community organization permits because it still has to be done manually with bring all the files to the BKBP office. For this reason, this research will overcome these problems by utilizing technology through the development of a monitoring information system for community organizations, where this system can be used for registration of permits for community organizations, viewing activity reports, monitoring organizational activities, and reporting organizations that are troubling the community. This system is web-based using the PHP programming language and the Laravel framework.

This study aims to (i) determine the effect of adding glass bottle waste aggregate and coconut fiber ash to the characteristics of the bricks and (ii) to determine the composition of mixing glass bottle waste aggregate and coconut fiber ash so that bricks with optimal characteristics are produced. The materials used in this study were glass powder, coconut fiber ash, and clay with a composition of glass powder, coconut fiber ash, and clay 0%:0%:100%, 5%:5%: 90%, 10% :10%:80%, 15%:15%:70%, and 20%:20%:60% with a FAS of 0.5. The process of making bricks is done manually. Characterizations carried out include: compressive strength, water absorption, and density. The addition of glass bottle waste aggregate and coconut fiber ash as a substitute for clay has an effect on the characteristics of the bricks. As the amount of glass powder and coconut fiber ash increases, the compressive strength value tends to decrease, the water absorption value tends to increase, and the density value tends to decrease. The compressive strength values in all compositions of mixing glass powder, coconut fiber ash, and clay still do not meet the SNI 15-2094-2000 standard. The value of water absorption at the composition of 5%:5%: 90% and 10%:10%:80% already meets the standards of SNI 15-2094-2000.

Student aspirations are various demands that are packaged in students' creative ideas that propose a process of changing something. There is no aspiration complaint service system at the Fakultas Sains dan Teknologi, Universitas Islam Negeri Sumatera Utara. So that students do not have a place to express their aspirations. Along with the development of technology, a web-based student complaint application was made which is equipped with the AES (Advanced Encryption Standard) algorithm which is able to secure student aspiration messages so that the aspiration messages conveyed by students cannot be read by other students, so that student aspiration messages are more confidential. The design and manufacture of this web-based public complaint application uses the waterfall model. The waterfall model begins with the analysis stage, namely by analyzing and collecting data through interviews with students and the Administration of the Faculty of Science and Technology, the system design stage, namely by designing the system interface, the system coding stage, and this stage ends with the system testing stage. Carried out to determine the feasibility of the system.
